Subject[PATCH v2 0/2] thermal: rcar_gen3_thermal: fix IRQ issues
There are issues with interrupt handling in rcar_gen3_thermal driver.

Currently IRQ is remain enabled after .remove, later if device is probed,
IRQ is requested before .thermal_init, this may cause IRQ function be
triggered but not able to clear IRQ status, thus cause system to hang.

Since the irq line isn't shared between different devices,
so the proper interrupt type flag should be IRQF_ONESHOT.

This patch-set fix these interrupt handling retated issues.

v2: use irq type IRQF_ONESHOT instead of IRQF_SHARED
disable interrupt in .remove

v1: initial version

Jiada Wang (2):
thermal: rcar_gen3_thermal: fix interrupt type
thermal: rcar_gen3_thermal: disable interrupt in .remove
